This function implements a basic form of rate distortion optimization (RDO) for UASTC. It only changes selectors and then updates the hints. It uses v

Returns false if the block uses 3-color punchthrough alpha mode, which isn't supported on some GPU's for BC3.

writes RG

We only support CC_MIXED non-alpha blocks here because that's the only mode the transcoder uses at the moment.

PVRTC2 is currently limited to only what our transcoder outputs (non-interpolated, hard_flag=1 modulation=0). In this mode, PVRTC2 looks much like BC1

Only supports the basic DirectX BC texture formats. gpu_images array is: [face/layer][mipmap level] For cubemap arrays, # of face/layers must be a mul
